摘　　要：元谋地震台水化观测站气氡脱气装置由于脱气效果较差,排水口堵塞及输气管堵塞等干扰,严重影响气氡观测质量,在2016年由溅落式脱气装置改造为自吸气鼓泡式脱气装置,经过2017年一整年的气氡连续观测,发现自吸气鼓泡式脱气装置存在由于水质较差,排水口堵塞问题,需要每周清洗一次脱气装置,因此重新改造为溅落式脱气装置。改造后,通过一整年的观测数据分析,较脱气装置改造前相比,气氡值明显升高,气氡观测稳定性明显提升,观测数据不受脱气装置影响。Due to the poor degassing effect of the gas radon degassing device in Yuanmotai hydration observa⁃tion Station,the blockage of the drainage outlet and the blockage of the gas transmission pipe and other inter⁃ference,the observation quality of the gas radon was seriously affected.In 2016,the sputtering degassing de⁃vice was transformed into a self-aspirating bubbling degassing device.After continuous observation of the gas radon in 2017,it was found that the self-aspirating bubbling degassing device existed due to poor water quali⁃ty.Because of the blockage of the drain outlet,the degassing device needs to be cleaned once a week,so it is rebuilt into a sputtering degassing device.After the transformation,through the analysis of observation data for a whole year,compared with before the transformation of the degassing device,the gas radon value is signifi⁃cantly increased,the observation stability of the gas radon is significantly improved,and the observation data is not affected by the degassing device.
